Hello Botolo,
Thanks for all.
mydomain.com.br is only a sample name. The real domain name is: drthiagoduarte.com.br
I following the sugestion of the Rone and create the adicional DNS record in my DNS server.
mx10.drthiagoduarte.com.br A 201.33.19.223
But does not work.
The nslookup output:
# nslookup
> set q=mx
> drthiagoduarte.com.br
Server: 192.168.2.1
Address: 192.168.2.1#53
Non-authoritative answer:
drthiagoduarte.com.br mail exchanger = 10 mx10.drthiagoduarte.com.br.
Authoritative answers can be found from:
drthiagoduarte.com.br nameserver = b.sec.dns.br.
drthiagoduarte.com.br nameserver = a.sec.dns.br.
a.sec.dns.br internet address = 200.160.0.11
a.sec.dns.br has AAAA address 2001:12ff::11
b.sec.dns.br internet address = 200.192.232.11
If I send messages from email (noticias@drthiagoduarte.com.br) to a external mail (like gmail), the message appears:
Quote
Erro SMTP (550): Falha ao adicionar o destinatário "marcelo@comdesk.com.br" (5.1.1 <marcelo@comdesk.com.br>: Recipient address rejected: User unknown in virtual mailbox table)
if I send messages from a external email, the message is returned:

The error that the other server returned was: 451 451 4.3.5 Server configuration problem (state 13).

Marcelo
